WebFor the p-GaN HEMT without an FP (Figure 1a), most of the potential lines were concentrated around the drain side of the gate, which indicates that a high electric field peak can form for this device. For the p-GaN HEMTs with FP layers, high potential line density was observed at the drain side of the gate edge and the edges of FP1, FP2, and FP3. WebThis paper compares GaN-on-Si High-Electron-Mobility Transistors (HEMT) device characteristics under a High Humidity, High Temperature, Reverse Bias (H3TRB) Test. Twenty-one devices from three manufacturers were subjected to 85 °C and 85% relative humidity while blocking 80% of their voltage rating.
WebIn this study, we investigated enhance mode (E-mode) p-GaN/AlGaN/GaN high-electron-mobility transistors (HEMTs) with an Al0.5GaN etch-stop layer. Compared with an AlN etch-stop layer, the Al0.5GaN etch-stop layer not only reduced lattice defects but engendered improved DC performance in the device; this can be attributed to the lattice match …
